' To all whom t concern ide it known that l, ALFRED ANGERS, a

. subject of the King of Great Britain, residing at Black Lake, in the Province of Quebec, Canada, have invented certain new and useful improvements in Asbestos-Fiber Sep- .arators; and ll do hereby declare that the following is a full, clear, and exact descrip'- tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rllhe present invention relates to new and useful improvements in an asbestos fiber separator.

The primary object of the invention is the provision of a machine for the separation and extraction of asbestos fiber from the tails after the tailing-screens in order to make a further use of material, which ordinarily goes to waste. Another object of the inventlon, is the provision of a machine of the above speciiied type, so constructed that when the material, which ordinarily goes to waste passes through the machine, a certain amount of asbestos fiber, will be extracted therefrom, for further use.

Another object of ,the invention, is the provision of a machine of the above specified type, including a hopper, and a compartment through which the material passes, the said compartmentbeing provided with means for separating the ber from the remaining waste material, and extracting it from the machine, for further use.

A still further object of the invention, is the provision of a machine ,of the above specified t pe, which will be comparatively simple an inexpensive to manufacture, reliable and efficient in use, and readily operated. l With the above and other objects in view, the present invention resides in the novel features of construction, formation, combina'- tion, and arrangements of parts, to be here- Specication of Letters Patent. vmmgQ/@dl Jun@ 133g 1922 Application led .tune le,

ing, by corresponding characters of reference, throughout the several views, the numeral. 5 designates in general my improved asbestos iber separator,'which consists of aopening 16, which communicates with the compartment 13, and in which is disposed, the lower end of a hopper 17 into which is fed the waste material from the tailingscreen, of any well known separator (not shown in the drawing).

A feed roller 18, is mounted below the hopper 17 and disposed at one side thereof are a plurality of fingers 19, which co-operate, with the roller by feeding the contents slowly intothe upper end of the compartment 13.

A plurality of. downwardly inclined frames 20 are mounted upon opposite sides of the compartment 13, as shown in Figure 1 of the drawing.

Balehplates 21 are adjustably mounted upon the frames 20, in order to regulate the space, through which the contents of the hopper 17 Hows.

o-o erating plates'22`, which are likewise incline downwardly, are secured to thepartitions 12 adjacent the free ends of the baiile plates 21, and these plates. may be hingedly mounted and serve to retard the How of the contents through the compartment 13, from its upper end to its lower end.

@penings 23 are formed in the partitions 12 below the plates 22 and the material at the lower end of the openin is inclined upwardly, in a direction opposite to that of the plates 22. 'llhese openings provide passages through which the ber is adapted to be drawn in a manner 'to be hereinafter described.

.Plates 25 are secured to the lower ends of the partitions 12, and to theA upper ends by the pipes 26, which .extend through the top ll into the upper end of the compartments la.

lin operation the material is fed into the hopper 17, from which it passes downwardly through the compartment 13, striking the baffle plates 2l and 22, which retard its movement and after passing below the baille plates the suction through the pipes 26 and 27, draws the fibrous material upwardly through the openings 22, and dlscharges it to any desired locallty. The material passing through the opening 15 at the lower end of the housin 6, is the waste material which may be carried to any desired locality, for dumping purposes.

lF rom the foregoing description taken in connection with the accompanying drawing, it will be manifest that a separator for asbestos fiber is provided which will fulfil all p ofthe necessary requirements of. such a device, eliminatlng any waste in the machlnes now 1n common use, and 1t should be understood in this connection, that various' therein, providing communication between the central and side compartments, plates secured to the inner side of the central-compartment above the openings and inclined downwardly,bafiie plates arranged in staggered relation, and extending toward the ends of the first mentioned plates, suction' pipes extending into the side compartments, at the upper end thereof, and inclined plates leading from the lower end of the partltions to the upper end of the side compartments, substantially as, and for the purposes `set forth.

2. ln a machine of the character described, the lcombination of a housing, partitions located within said housing and dividing the latter into central and side compartments, said partitions having openings therein, providln communication between the central and side compartments, plates secured to the inner side of the central compartment above the openings and inclined downwardly, baffle plates arranged in staggered relation and extending towards the ends of the first mentioned plates, means for adjustably supporting said baille plates, suction pipes extending into the side compartments, at the upper end thereof, and inclined plates leading from the lower end of the partitions to the upper end of the side compartments,

substantially as and for the purposes set forth.

It .witness whereof I have hereunto set my hand.

ALFRED ANGERS.
